Title: Video game program, recording medium having recorded video game program, character moving control method in video game and game apparatus
Inventor: NAKAZATO HISAYOSHI
IPC: A63F13/426
Filed: 2001-03-29
Abstract: PROBLEM TO BE SOLVED: To enable smooth movement of characters while simplifying operations. SOLUTION: Angles θ are always detected between the line of vision of a camera and the line of direction in which the player's character faces (S1). When the direction key is operated by players, the input direction by the direction key operated is corrected by the angles θ to generate the resulting direction as go-ahead direction of the player's character (S3). Moreover, the go-ahead direction of the player's character is stored (S4) and the player's character is moved in the go-ahead direction (S5). When the operation by the key part for the same direction is continued at the direction key (S6: YES), the player's character is moved within a three-dimensional space in the go-ahead direction stored by the processing at S4 whether the line of sight shifts or not.  Therefore, even if three-dimensional space images change in a display pattern, the player's character is moved continuously in the same direction within the three- dimensional space.
